写在赛后两天洛谷的民间数据出来了，貌似只有290？（100+100+0+60+10+20）。Day1T3 hash表没初始化，全炸了？Day2T1 写堆貌似贪心是错的？Day2T2 DP不会打又炸了？Day2T3 不会傻逼枚举然后贪心贪错了，直接20分搞到滚粗？290分在FJ能搞到省二左右（也是踩线），ZJ目测就直接出局了。
这两天过得真的很难受，各种想法都在脑子里浮现：辛辛苦苦努力了一年然后

解题过程考虑图论模型，即如果A和B能转化成C，那么便在A.B和C中连一条边，然后就直接跑dijkstra，每次取出最小的花费val[i]去更新其他药水的花费，当然这里的其他药水必须是已经更新过了的，至于方案数的话乘法原理一用就跑出来了.

            线段树的定义线段树(segment tree)是一种二叉搜索树，与区间树相似，它将一个区间划分成一些单元区间，每个单元区间对应线段树中的一个叶结点。使用线段树可以快速的查找某一个节点在若干条线段中出现的次数，时间复杂度为O(logN）。而未优化的空间复杂度为2N，因此有时需要离散化让空间压缩。
线段树的作用

问题分析首先假设当前存在区间[l,r]，那么如果我们能用O(1)的时间返回这个区间的最大值所处位置a，以及最小值所处位置b，如果ab,则对三段分别进行递归调用即可解决问题。那么，我们需要怎么样事先处理好区间[l,r]的最大值呢？
